African-American pastors aren't as scary as white pastors. When Rev. Wright speaks, he's trying to get people active in positive social ways. A white pastor yelling, 'God damn America!' probably has a copy of The Turner Diaries on his shelves and a set of white sheets hanging in his closet, and wants people to go out and blow things up and overthrow the government in the name of a fantasy.
African-American pastors' main concern is speaking truth to power, and to dragging America (kicking and screaming) to its potential. They poke the status quo with sticks, while white guys like Hagee (and Robertson) want to become the arbiters of the status quo.
